Updating Hierarchies

The update hierarchy export option allows you to add or remove objects from a hierarchy while preserving any sequences that have already been exported. The new hierarchy should be set up in the Max scene, in the same way as for exporting a hierarchy in the first place. After choosing the update hierarchy option, and choosing the appropriate hierarchy, you will be shown a list of changes to the hierarchy, consisting of three lists of objects.

Objects that are being removed from the hierarchy will also be removed from all the sequences currently within the rif file. Objects that are being added, however, need to be given animation data for all of the sequences that already exist. It is assumed that the new objects will remain still relative to their parents throughout all of the sequences within the rif file. The relative position taken , is the positioning of the object relative to its parent in the Max scene that is being used for the export. For example, if you are adding a hat to the hierarchy, you should make sure that it is positioned correctly relative to the head (assuming the head is its parent) when updating the hierarchy.
